Deformation Behavior of Optical Ceramic Nanomultilayers: The Role of Aperiodicity

open access: yesAdvanced Engineering Materials, EarlyView.
Ceramic nanomultilayers demonstrate optical and mechanical behavior tunability through aperiodicity. Within the studied systems, optically optimized coatings exhibit an average ultraviolet, visible, and near‐infrared spectral transmittance above 90%.

Matrix Tropism Influences Endometriotic Cell Attachment Patterns

open access: yesAdvanced Functional Materials, EarlyView.
The influence of substrate stiffness and multicellular coculture on endometriotic cell attachment to extracellular matrix‐laden microarrayed islands is reported. This model investigates early endometriotic cell attachment, aiming to capture “lesion initiation events”.

A Transparent Semicrystalline Polymer Used in Thermally Responsive Smart Window Application

open access: yesAdvanced Functional Materials, EarlyView.
A thermally responsive smart window is fabricated based on a transparent semicrystalline polymer via copolymerizing stearyl acrylate and ethoxylated trimethylolpropane triacrylate. The high transparency is achieved by restricting the crystal domain to nanometer size via ultraviolet curing at a high temperature.

The Light Hadron Mass Spectrum with Non-Perturbatively O(a) Improved Wilson Fermions [PDF]

open access: yes, 1996
We compute the light hadron mass spectrum in quenched lattice QCD at $\beta = 6.0$ using the Sheikholeslami-Wohlert fermionic action. The calculation is done for several choices of the coefficient $c_{SW}$, including $c_{SW} = 0$ and the recently ...
